Homogenization methods applied to model the thermomechanical behavior of shape memory alloys
Laboratoire de Physique et Mécanique des Matériaux (UMR CNRS 7554), Ecole Nationale Supérieure des Arts et Métiers de Metz, France
Modem scale transition methods are used to establish the thermomechanical behavior of shape memory alloys. Physical mechanisms responsible for the observed phenomena are considered and two differents models are used to deal with intra and intergranular effects. Discrete internal variables description is used to determine constitutive equations for single crystal and a self-consistent method is used to derive the polycrystalline response. Overall behavior so computed shows excellent agreement with experimental measurements.
